请同时参阅图7-9,图7-9为本实用新型另一种实施方式,该实施方式提供了另一种发声器件100a,发声器件100a与发声器件100基本相同,两种实施方式的主要区别点在于:球顶与振动部的粘合位置不同。
所述发声器件100a中,所述包边部25a由所述振动部21a远离所述磁路系统3a的一侧凸出形成,所述球顶24a贴合于所述振动部21a远离所述磁路系统3a的一侧。该结构使得所述球顶24a与所述振动部21a胶水的位置位于所述发声器件100a的外侧,有利于降低制作过程以及后期有对发声器件100a内部产生异物的风险。
具体的,所述球顶24a远离所述磁路系统3a的一侧与所述包边部25a远离所述磁路系统3a的一侧位于同一平面。该结构有利于发声器件100a的声学性能,同时也易于组装加工。
与相关技术相比,本实用新型的发声器件将通过将振膜自振动部凸出形成的包边部,并设置包边部呈台阶状并形成台阶差,并将球顶收容于台阶差内并位于包边部远离折环部的一侧。该结构有效控制球顶与振动部胶合时溢胶问题,使得胶水不污染折环部的曲面,降低制作过程以及后期有对发声器件内部产生异物的风险,避免发声器件出现性能不良的现象,并改善发声器件打胶胶合状态外观一致性,还增加球顶与振动部胶合区域的结构强度,从而使得本实用新型的发声器件的可靠性好。
